The Mix Fresh B4_Jx Leak Exposed 1,365 U.S.-Linked Login Credentials

On 11-Apr-2026, HEROIC analysts identified a combolist named "Mix Fresh B4_Jx" after it was uploaded by a Telegram user. The file is tied to United States accounts and contains 1,365 records pairing email addresses with plaintext passwords and associated login URLs. Why This Is Dangerous Because the passwords in this file are stored in plaintext and matched to specific login URLs, an attacker does not need to do any extra work to use them. They can try each email and password combination directly against the site it belongs to. Anyone in this batch of 1,365 accounts who reused their password elsewhere can be logged into instantly by someone with access to the file. What Was Exposed Email addresses Plaintext passwords Associated website URLs (the login pages tied to each credential) Why This Matters "Fresh" combolists like this one are prized by attackers precisely because the credentials are newer and more likely to still be valid. The email, password, and URL combinations get run through automated credential stuffing tools that test logins against banking sites, email providers, and social platforms. Anyone whose information is in this file and who reuses passwords across accounts faces a real risk of account takeover, identity theft, and financial fraud. How a "Fresh Mix" Combolist Is Assembled A combolist is a plain text file of email and password pairs, typically gathered from recent phishing pages, malware-infected devices, or newly breached services and then repackaged for resale or free distribution. Files labeled "fresh" or "mix" on Telegram signal to buyers that the credentials are recently collected rather than recycled from old, well-known breaches, making them more valuable and more likely to still work. Check If You Are Affected With 1,365 email and password pairs exposed in this leak, it is worth checking whether your information is included. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including combolists like this one, and tells you immediately if you have been exposed.
